Abstract
The utility model relates to a vibration platform calibration tool used for en eddy-current transducer. The vibration platform calibration tool used for the eddy-current transducer includes a support pedestal made of cast iron material, a flange plate installed on the lower end of a vertical support rod fixedly, the vertical support rod connecting the flange plate with the pedestal through the flange plate of the support rod and periphery threaded holes and disposed upward vertically through flange connection, sleeve through holes arranged in an end part of the vertical support rod uniformly and downwardly, a bolt used for fixing sleeves and matched with the sleeve through holes, a sleeve penetrating through one of the sleeve through holes transversely, a horizontal support rod penetrating through the sleeve transversely, a fastening bolt used for mounting a clamp on an end part of the horizontal support rod and a vibration element disposed below the clamp. Compared with a traditional threaded assembling method, the vibration platform calibration tool used for the eddy-current transducer can realize quick installation and dismounting, so that working efficiency can be improved distinctively and labor strength is reduced. At the same time, since the vibration element has a certain vertical height, so that a specific distance can be kept between a probe and a vibration platform. Therefore, electromagnetic interference caused by a vibration generator on the eddy-current transducer can be avoided and calibration accuracy is improved.
Description
Technical field
The utility model belongs to electrical measurement equipment field engineering field, especially a kind of shaking platform eddy current sensor calibration tool.
Background technology
The vibration transducer verification platform used at present adopts bolt to be fixed sensor.Table top is equipped with a disk, has the threaded hole of multiple diameter on disk and is furnished with corresponding bolt.Size according to difference probe bottom thread aperture during verification is fixed on corresponding position.To drive like this probe vibration together when platform is vibrated, thereby reach the purpose of check sensor.Current this installation of sensors mode is only applicable to speed and acceleration transducer, because these two kinds of probes are all to carry out the excitation response signal by self vibration.And this method is just inapplicable for eddy current sensor, because descend in working order eddy current sensor itself, be vibration-generating not.Under duty, the eddy current sensor top is connected with high-frequency current, and this electric current can excite electromagnetic induction on the conductor closed on, and eddy current sensor judges the vibration state of this object by surveying this induction.Therefore to realize just must realizing the simulation of its duty to the verification of eddy current sensor.Therefore need a kind of new-type eddy current sensor calibration tool to realize the verifying work of eddy current sensor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of shaking platform eddy current sensor calibration tool is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of shaking platform eddy current sensor calibration tool, comprise the bracket base that adopts cast iron materials to make, be packed in the ring flange of vertical pole lower end, by the ring flange of pole, with the circumferential thread hole on base, the two is connected, the vertical pole made progress by the flange vertical connecting, the sleeve perforation that vertically evenly make downwards the pole end, with each sleeve, bore a hole to being applied to the bolt of fixed muffle, cross the sleeve in the sleeve perforation, cross the horizontal strut in sleeve, the horizontal strut end is for the fastening bolt of assembling jig and the vibrating elements that is placed on the fixture below.
And described fixture also further comprises the rubber blanket that is bonded in fixture two intermediate plate inboards.
And described vibrating elements height is between 15-20CM, the vibrating elements top is level and smooth, and lower end is shaped with screw thread.
And the thickness of bracket base is 3cm, diameter is 30cm.
And the sleeve perforation that evenly make downwards described vertical pole end has 4 altogether, the distance on each sleeve perforation vertical direction is 5cm.
Advantage of the present utility model and good effect are:
1. this calibration tool adopts the spring clip type fixture to be fixed sensor, compares conventional threads assembling mode and can realize Fast Installation and dismounting, will significantly improve work efficiency when popping one's head in a large number verification, reduce labour intensity.
2. the utility model adopts innovative design to make the shaking platform that can only carry out speed and acceleration transducer verification equally also can carry out verification to eddy current sensor.Improve working method, widened working range, improved working efficiency.
3. vibrating elements adopts special material to make to have good electromagnetic induction characteristic, makes the Vibration Condition that detects this element that probe can be sensitiveer.
4. vibrating elements has certain vertical height, this just can so that the probe can maintain a certain distance with shaking platform, thereby avoid vibration machine to eddy current sensor electromagnetic interference (EMI), improved the verification accuracy.
